TAMPA, Fla. - Jacoby Ellsbury, sidelined by an oblique strain, on Thursday vowed to be ready for the Yankees' April 6 season opener. "I feel very confident that I'll be there Opening Day,'' Ellsbury said.

Ellsbury was scratched from the lineup Tuesday and went for an MRI on Wednesday after the Yankees initially said he didn't need one. Ellsbury said the change of heart was the team's and didn't indicate any increased level of concern or discomfort on his part from one day to the next. "It actually felt better,'' he said. "But I think they just wanted to be 100 percent, just to make sure.''

Ellsbury last played Sunday. The Yankees' revised timetable after the MRI called for him to be shut down for a week.

Last season, Ellsbury didn't play in a major-league exhibition game after March 14 because of a strained calf. He got at-bats in minor-league games and was ready for the season opener.

"I'm fully confident that I'll be there on Opening Day, ready to play,'' he said.
